MiniLaTeX

The MiniLatex package renders a subset of LaTeX to Html. For a demo, see MiniLatex Live or www.knode.io. There is a technical discussion in the see the Hackernoon article, Towards LaTeX in the Browser.

Example

import MiniLatex
import MiniLatex.Render exposing(MathJaxRenderOption(..))


text = "Pythagoras says: $a^2 + b^2 = c^2$"

macros = "" -- your macro definitions

MiniLatex.render NoDelay macros text

See the code in ./example

NOTE: (a) macro definitions can be either the empty string or a multiline string of definitions. (b) With the transition to MathJax 3, macro definitions are not working. I will have a fix soon.

For interactive editors and live rendering, you may want to use the functions in MiniLaTeX.Edit. For an example of how this is done, see the code in ./demo

This release

• Added a source map. This is a dictionary whose keys are pieces of source text and whose values are the ids of the corresponding rendered text. With a little more work, this will allow one to have bidirectional sync between source and rendered text: click on something in one to bring the corresponding part of the other into focus.

Recent releases

• Better LaTeX error reporting (to be still further improved).

• The below is used to optimize rendering by MathJax

    type MathJaxRenderOption = Delay | NoDelay

  This is necessitated by the single-threaded nature of Javascript.
